Within each compartment a metal ring 2.() otY V cross section is arranged, the middle edge of which is directed inward and serves in c njunction with tiie spiders 18 as a support for the inner supporting surfaces 2l which are made of the same material as the sustaining surfaces i9, Giving to this arrangement cach compartment has a double conical internal surface with the narrower ends abutting against each other7 the forward cone in the construction illust-rated being steeper.r While the rearward cone has a correspondingly small angle. in this manner, owing to the equal pressure of the air and the escaping gases on the front cone surfaces and the pressure of the layers of air between the abutting edges of thc two cone surfaces, a straight flight without deviations and a fa if'orable driving forward of the Whole torpedo and flying device are obtained, while the stepovise rearward diminution of the sustaining compartmentsy makes possible the full use of the carrying power of the air and gas flowing therethrough. On the up er side of the foremost compartment a surface 'which is preferablyV constructed of elastic material is tixed by meansof screws 2st passed through longitudinal slots 23 in said surface, in such a manner that it. projects more or less beyond the front edge of said compartment. This surface 22 will be bent more or less upward during flight as it meets the air and thus determines the trajectory.

For launching,4 the torpedo together with the tubular shaft 4 is placed on a tube or bar 26 arranged on a stand .25 and caught by :i trigger or catch 27. rlie desired elevation can he given to the tube by means of Wheel Q8 according to which the above mentioned elastic surface 22 is also adjusted. To render the aiming device stable a weight 29 may ne suspended from the stand. When the torpedo has been aimed the charge in the drum is ignited; the gases evolved set the turbine Wheels together with the propeller blades l? rotating and on attaining the nec essary speed of rotation the pull exerted overcomes the pull of the trigger 27 and the torpedo is free to perform its Hight..
